The game features a command that displays your playtime on a specific character down to a minute. Would it be possible to use it to act as a timer for a full game run? Another idea would be to use it to break up sections of a full game run by using it before and after a section of the run so the runner can take breaks and have proof they didn't do anything in game. This might open up the full game runs to more people if they don't have to dedicate a literal day to attempt it.

as much as that might be a good idea all it takes is one person leaving it on once to fuck up their entire run

The MSQ runs can be done in either A single session "SS" or across multiple days as a multi session "MS". A run can use in game time "IGT" or real time through the use of Livesplit ect.

Hmm yeh thats true
